Frequently Asked Questions

Can I get prescription lenses put in KNEX frames?

Yes, all KNEX eyeglass frames are designed to accommodate prescription lenses. You can take your frames to any licensed optician along with your current prescription to have lenses installed. Designer Optics also offers prescription lens services, allowing you to order your KNEX frames with lenses already installed. The frames accept single-vision, bifocal, progressive, and high-index lenses depending on your vision correction needs.

What is the price range for KNEX eyeglasses?

KNEX eyeglasses typically range from approximately $38 to $85 for frames only. This pricing makes KNEX one of the more affordable optical frame brands available, allowing you to purchase multiple pairs or replace frames without significant expense. Prices may vary slightly by style and any current promotions.

Are KNEX frames suitable for strong prescriptions?

KNEX frames can accommodate a range of prescription strengths, including higher prescriptions when paired with high-index lenses. The full-rim construction in many KNEX styles provides good support for thicker lenses. However, if you have a very strong prescription, consult with your optician about which frame styles will work best—generally, smaller lens widths and rounder shapes help minimize lens thickness and weight.

Do KNEX eyeglasses come with a warranty?

Warranty coverage varies by retailer. When purchasing KNEX frames from Designer Optics, check the specific warranty terms at checkout. Most optical frames come with manufacturer protections against defects in materials and workmanship. Keep your receipt and contact customer service if you experience any issues with frame construction or hardware failure.

How do I know which KNEX frame size will fit me?

Each KNEX frame listing includes measurements for lens width, bridge width, and temple length (usually shown as three numbers, like 52-17-140). Compare these to your current glasses' measurements, which are often printed on the inside of the temple arm. Generally, lens widths of 50-54mm suit most adults. If you're between sizes, consider your face width—wider faces typically need lens widths of 54mm or larger, while narrower faces work better with 50-52mm.

Can I return KNEX frames if they don't fit?

Return policies depend on the retailer and whether lenses have been installed. Designer Optics offers returns on frames in original condition—check the specific return window and conditions on the website. If you've had prescription lenses installed, returns may be limited since the frames have been customized. Always verify the return policy before purchasing, especially if you're unsure about fit or style.
